Specifications

1. stored in a cylinder
2. a kind of compressed liquefied gas
3. non-destructive to ozone layer in the atmosphere

Hexafluoropropane(HFC236fa)extinguishant stored in a cylinder is a kind of compressed liquefied gas, which is colorless, non-corrosive, non-conductive and non-destructive to ozone layer in the atmosphere. Hexafluoropropane (HFC236fa) extinguishant is an ideal substitute of Halon 1211, suitable to fill a protection, also suitable to the site having man of all flooding.

Q:Inorganic chemistry employment direction? Current research direction
Inorganic chemistry is the science of the composition, nature, structure and reaction of inorganic matter, which is the oldest branch of chemistry. Inorganic substances include all chemical elements and their compounds, except for most of the carbon compounds. (In addition to carbon dioxide, carbon monoxide, carbon disulfide, carbonates and other simple carbon compounds are still inorganic substances, the rest are organic matter.) Inorganic chemistry is in addition to hydrocarbons and their derivatives, the nature of all elements and their compounds And their reaction to experimental research and theoretical interpretation of science, is the development of the discipline of the earliest branch of a discipline.
Q:Artemisinin is not a derivative of hydrocarbons
There are many types of hydrocarbons, flammable and explosive materials, the structure of the known hydrocarbons in more than 2000. The hydrocarbon is the parent of the organic compound, and the other various organic compounds can be regarded as derivatives of one or more hydrogen atoms in the hydrocarbon molecule being replaced by atoms or radicals of other elements.
Q:What is the reason why the battery's energy density is much lower than the hydrocarbon?
The battery is carrying the oxidant, and the hydrocarbon is the air as an oxidant direct reaction, which is less than the rocket engine than the jet engine than the reasons for the red.
Q:Carbon compounds (except inorganic carbon compounds), hydrocarbons and derivatives of the general term is?
Organic matter
Q:Ionic compounds, covalent compounds, electrolytes, non-electrolytes, which are both compounds and inorganic compounds
An electrolyte is a compound capable of being conductive in an aqueous solution or in a molten state, such as an acid, a base and a salt. Those compounds that can not be electrically conductive in the above cases are non-electrolytes such as sucrose, alcohol and the like.
Q:What is the definition of organic matter
Organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.
Q:What is the difference between an aromatic compound and a hydrocarbon derivative?
The aromatic compound is a benzene ring containing compound, which may be a hydrocarbon or a hydrocarbon derivative. Hydrocarbons are hydrocarbon-containing compounds, and hydrocarbons containing hydrocarbons other than hydrocarbons are derivatives of hydrocarbons. The two concepts have crossed.
Q:Why does toluene not belong to the derivatives of hydrocarbons?
Hydrocarbon: sound tīng, is composed of two elements of carbon and hydrogen organic compounds known as hydrocarbons, also known as hydrocarbons. It reacts with chlorine, bromine, oxygen and other hydrocarbons to produce derivatives of hydrocarbons. Such as methane and chlorine in the light conditions of reaction to produce methyl chloride, dichloromethane, chloroform and chloroform (carbon tetrachloride) and other derivatives. The concept of derivatives is hydrocarbon and chlorine, bromine, oxygen and other reaction products. While toluene is not methyl and benzene, she is a whole noun is aromatic. Also known as aromatic hydrocarbons. Generally have one or more six-ring (benzene ring) with a special structure. The simplest aromatic hydrocarbons are benzene, toluene, xylene. There is also naphthenes. As the name suggests it is a ring structure. The most common is the five carbon atoms or six carbon atoms of the ring, the former called cyclopentane, which is called cyclohexane. The molecular formula of the cycloalkane is of the formula CnH2n. Cycloalkane is also called cycloalkane hydrocarbons. And alkanes. Is a carbon atom between the single bond phase chain hydrocarbon. Since the number of atoms that make up the hydrocarbon and hydrogen is different, the result is that the petroleum contains hydrocarbon molecules with large and small differences. Alkanes are named according to the carbon atoms and numbers contained in the molecule, and the number of carbon atoms is less than 10, from 1 to 10, followed by a, B, C, D, E, G, Alkane to say that the number of carbon atoms in more than 11, with the number that thank you to adopt
Q:Is it possible to understand that organic matter is contained in the heat of inorganic matter?
Understand enough messy
Q:Will AsH3 (arsenic trioxide) is organic or inorganic
AsH3 (arsine trihydride) is not containing C element
